Answer:
Step-by-step explanation:
<h3>Equation of the blue line:</h3>
since the line is horizontal and passes <u>-</u><u>2</u> the equation of the blue line should be
<h3>Equation of the red line:</h3>
remember The form of equation of a line
where m is slope of the line and b is the y-intercept we can clearly see that the red line crosses y-axis at (0,-3) therefore b=-3
to figure out m we can consider the following formula:
from the graph we acquire ∆y=1 and ∆x=2
thus substitute:
so we have figured out m and b
therefore our equation of blue line is
our given options are in standard form so
move -3 to left hand side and change its sign:
cross multiplication:
move 6 to right hand side and x to left hand side and change its sign
multiply both sides by -1:
hence, our system of linear equation is
Answer:
B
Step-by-step explanation:
The circle has to be hallow in order for it to be greater than or less than. The arrow is going below 4 because the circle is on 4 and the arrow is pointing to the left side.
Answer:
If your trying to simplify then your answer would be 
Answer:
C and E
Step-by-step explanation:
The change in elevation was 44 + 20 = 64 m
the rate of fall was 64 m / 32 s = 2 m/s
The anchor reached the surface in 44 / 2 = 22 s so C is valid
E is correct as the ocean surface is origin and <u>Up</u> is the positive direction.
The anchor starts at 44 m above the surface and position is lower by 2 meters every second
Answer:
y=2/3x-3
Step-by-step explanation:
first we fill in the values for y=2/3x to find y intercept
-5=2/3(-3)
-5=-6/3
-5=-2
We know in order to make this equation true we have to subtract 3 so we write the new equation like this
y=2/3x-3
And we can test it
-5=2/3(-3)-3
-5=-6/3-3
-5=-2-3
-5=-5
